5. Sender transmitted Data is transmitted, on a single channel, one bit at a time one after another - Much faster than parallel because of way bits processed (e.g. USB and SATA drives) Receiver received Serial Transmission 1 0 1 0 0 1 1 0

11. - simplex: One direction only Transmission Direction
19. Uses an empty data packet called a token and a special protocol called “token ring”. Packets travel around the ring in a clockwise direction. Clients require an empty token to transmit data. Advantages - no collisions because all data travels in same direction. Disadvantages - fails if an individual node in the network fails Ring Topology
20. All data is sent from one client to another through the server. Advantages - If one client fails no other clients are affected. Disadvantages - If central file server fails the network fails. Star Topology
Editor's Notes
Easy to add extra computers . If computer goes down it doesn’t affect rest of network
